Server HDD Caddy (3.5")

thingiverse

I recently purchased a secondhand rackmount server from a seller on eBay, which has 10 hard drive bays but didn't come with any HDD caddies. The server hardware and case provided no clues as to who the manufacturer was, so I did some searching, but couldn't find other printable models that would fit properly in my server. As it happens, someone else might find themselves in a similar situation, so here's the tray I designed for my server. Specs: Compatible with 3.5-inch hard drives. Designed for bays that were about 0.75 inches tall and approximately 4.25 inches wide. The thickness is roughly 0.1 inch. Standard (counter-sunk) HDD case screws work great with this design. I listed the above dimensions as approximations because a small clearance was given to each to account for my 3D printer's inaccuracies, allowing the tray to fit into the server easily.
